Description

Technical Field

[0001] The utility model mainly relates to the technical field of thinning, and in particular to a backboard fixing tool for a thinning workshop. Background Art

[0002] The existing processing method for single-sided thinning (such as OLED screens) is a top-spray spray etching method. The glass substrate is first attached to the backplane, and then the backplane is loaded by the tooling fixture for etching production. The backplane is vertically inserted into the tooling fixture and then enters the processing machine. The acidic chemical liquid in the etching machine is sprayed from the top for etching production. The current tooling used in the spray etching method is an abacus bead support substrate, which is composed of bottom teeth, side teeth, and side baffles. The side teeth currently used are 35-tooth abacus bead side teeth, which are mainly used to fix the backplane in the setting frame for spray etching. Since the tooling has no other fixing method, the backplane will shake in the tooling, causing the distance between the backplanes to affect the liquid spraying of the substrate as the shaking occurs, resulting in uneven etching of the substrate glass after etching. On this basis, a backplane fixing tool for thinning workshops is proposed. Utility Model Content

[0022] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0023] Reference Figure 1-4 The present embodiment provides a back panel fixing tool for a thinning workshop, comprising a fixing plate 1, wherein the bottom surface of the fixing plate 1 is provided with a plurality of preset cavities with the bottom penetrating therethrough, a back panel 2 is provided in the preset cavity, a glass substrate 3 is provided on one side of the back panel 2, and connecting plates 4 are provided at both ends of the fixing plate 1 for fixing it to the production tooling.

[0024] In a preferred embodiment, the preset cavity is arranged in a trapezoidal shape to facilitate the installation of the back plate 2.

[0025] In a preferred embodiment, the fixing plate 1 and the connecting plate 4 are both made of PVC board, which is a strong material that is not easy to bend and has strong acid resistance to acidic liquids (HCl, H2SO4, HNO3, HF, etc.) at 20°C-80°C. It does not easily deform at production temperatures. The fixing plate 1 and the connecting plate 4 form a fixed tooling, which is installed on the original production tooling to play a fixing role. The connection method between the fixing plate 1 and the connecting plate 4 is not specifically limited, and can be an integrated setting or a detachable setting.

[0026] In a preferred embodiment, the top of the fixing plate 1 is designed to be arc-shaped, so that the spray liquid can flow along the top, reducing liquid accumulation.

[0027] In a preferred embodiment, the backboard 2 is an acid-proof plastic board. The glass substrate 3 is attached to the backboard 2 using acid-proof tape at a temperature between 30° C. and 50° C., and then the backboard 2 is placed in a production tool for production.

[0028] In a preferred embodiment, the connecting plate 4 is provided with grooves for fixing it. The grooves at both ends are provided to facilitate the use of bolts and nuts to fix the connecting plate (i.e., the fixing plate 1) on the production tooling for production use.

[0029] First, attach the glass substrate 3 to the backing plate 2 using acid-proof tape. Then, place the backing plates without the glass substrate 3 attached to them in groups of two onto the production tooling. First, set up a fixing tooling (including a fixing plate 1 and a connecting plate 4) on the production tooling. Move the fixing tooling downward so that each group of two backing plates fits into the gap between the trapezoidal fixing positions of the fixing tooling (i.e., within the pre-test cavity). Then, secure the fixing tooling with bolts and nuts.

[0030] When the fixing fixture is installed on the production fixture, the back plate 2 can be fixed so that the back plate 2 will not shake during the production process, thereby avoiding production risks. The two back plates 2 will be fixed face to face with the non-substrate surface using the fixing fixture, as shown in the diagram of the fixing of the two back plates. Figure 3 As shown, this can more effectively make the glass substrate surface area larger and the effect of the liquid medicine better.

[0031] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
